I now have two dumbo rc 6 channel sets and to be honest at £23:00 a go on ebay with the gyro receiver you wont regret getting one at all.
The couple of week wait from china via speedpack free shipping is a bit of a drag but both mine arrived within time and in perfect condition.
I honestly haven't found a thing i don't like about these transmitters they are a great piece of gear ie.. 4 AA batteries not eight, 400 to 500 meter range 6 Chanel with drift gyro (just turn the controller ch 6 knob to adjust it from 0 to 100%) easy setup apparently programable channels too (not tried this function) and 3ms response time its a no brainer guys,,
Use all the cash you save for other upgrades..
